WHIP-CO RE.

EPECIFICATIQN forming part of Letters Patent No. 327,746, dated October 6, 1885.

Application filed March 21, 1885. Serial No. 159,647. (No model.)

.50 all whom it may concern.-

Be it known that we, ROBERT M. WILsoN, EDWARD M. Senna, and MAYNARD F. PEIROE, citizens of the United States, residing at Springfield, Hampden county, and State of Massachusetts, have invented a new and useful Improvement in IVhip-Cores, of which the following is a specification.

This invention relates to that class of whipcores in which whalebone combined with rattan is used to build up a core to be subsequently plaited and otherwise covered to complete the Whip; and our invention consists in forming one or more saw-kerfs in the rattan, from which the core is shaped, to extend from side to side of the rattan-piece and to longitudinally coincide with its axis, and in then filling said kerf or kerfs witha corresponding strip of whalebone, and gluing together the surfaces of whalebone and rattan in contact.

Heretofore in the process of strengthening and giving elasticity to the rattan cores of whips by uniting whalcbone therewith it has been common to form a central core of whalebone and build up the form of the core by an envelope of rattan strips disposed thereupon; but the size of the solid whalebone core required, from the growing scarcity of the material, renders it increasingly difficult to supply a whip of this class for general use. \Ve have found that by combining strips of whalebone, as above described, with the rattan to form a core, a whip is provided having the strength and elasticity of one with asolid central whalebone core, while the strips of whalebone may be no thicker than shavingboard, and may be formed of what would be waste in shaping a solid core.

\Ve are aware that saw-kerfs have been used in rattan cores to make a place for rawhide strips within said core, for the purpose of strengthening the same; but the rawhide adds no elasticity to the core and exerts no influence, as in the case of strips of whalebone, to keep the whip straight.

Our invention is fully illustrated in the ac companying drawings, in which Figure I is a portion of our improved core having strips of whalebone at right angles to each other in saw-kerfs in the rattan. Fig. II is the same with a semicircular piece removed, on the line as as. Fig. III is a transverse section. Fig. IV is a side view of a whalebone strip. Fig. V is an end view of the same. Fig. VI is a re duced view of a core, ready for covering. Fig. VII is a portion of a core having only one strip of whalebone, and Fig. VIII is a trans verse section of the same.

a is the rattan, b is a saw-kerf therein, and d is a strip of whalebone.

Although one strip of whalebone letinto and secured in the rattan, as shown in Figs. VII and VIII, illustrates the principle of our invention in re-enforcing the elasticity and strength of the rattan, we prefer to employ two strips, as shown in Figs. I, II, and III, the two strips intersecting each other at approximately a right angle, and at their intersection coinciding with the longer axis of the rattan. In combining these two strips (1 one such, as seen in Fig. IV, is first inserted and glued in a saw-kerf in the rattan, and the rattan turned at right angles has formed in it another kcrf through both rattan and whalebone, to receive the other strip to complete the core.

It is advisable when two strips at right angles to each other are used to let one extend nearer to the butt of the whip, to pre vent the whip when in use from bending too much at one point.

Now, having described our invention, what we claim is- As an improved article of manufacture, a whip -core consisting of a tapered rattan piece having longitudinal saw-kerfs and flat whalebone strips fitted into and secured in said kerfs by glue, substantially as described.
